IO::Multiplex is designed to take the effort out of managing multiple file handles. It is essentially a really fancy front end to the select system call. In addition to maintaining the select loop, it buffers all input and output to/from the file handles. It can also accept incoming connections on one or more listen sockets.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
Problem reports, updates or suggestions for this package should be reported with send-pr.
